RAIL-CHAIR.

Specification of Letters Patent. Patented Sept. 2'7, 1921.,

Application filed March 8, 1921. Serial No. 450,561.

T all whom it may concern Belt known that I, DAVIS AMBRosE, a

- citizen of the United States, residing at Louisville, in the county ofJefferson ,and State of Kentucky, have invented new and usefulImprovements in Rail-Chairs, of which the following is a specification.

My present invention has reference to an improved rail chair.

My primary object is to produce a rail chairconstructed of sectionsassociated in such a manner that the bending of the rails downward willautomatically cause a binding engagement between the chair and the saidrails.

A further object is to produce a rail chair comprising essentially twomembers shaped to receive the rails therebetween, a wedge elementresting on the base and underlying the rails in a manner that thebending of the rails on the wedge forces the latter against the base ofthe chair sections to cause a swinging or canting of the latter to bringtheir engaging portions into frictional contact with the flange and webof the rails, or with the base flange and side members of fish plateswhen the latter are employed, while novel means is provided for holdingthe wedge. between the chair and rails.

The foregoing, and other objects which will appear as the nature of theinvention is better understood, may be accomplished by a. construction,combination and operative association of parts, such as is disclosed bythe drawings which, accompany and which form part of this application.

In the drawings Figure 1 is a side elevation showing two rails securedto a rail chair in accordance with this invention.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view on the line 44 of Fig. 1. V

Fig. 5 is a perspective view looking toward the widened end of thewedge.

Fig. 6 is a similar view of the locking plate for the chair sections.

Referring now to the drawings in detail, two rails, of the ordinaryconstruction, are indicated by the numeral 1 respectively. The rails 1are connected together by angle bars 2 which tion.

improved rail chair comprises two simi ar members or sectionseach havinga substantially thickened block-like base 3 from which arises in a linewith its outer edge, a side plate 4 that has its upper extremity formedwith an inwardly directed are also of the usual construcflange 5. Theunder face of the flange 5 is arranged at an inclination, as indicatedby the numeral 6; The chair. sections are of a less length than theangle bars 2 and the base portion 3 of each of thesections graduallydecreases in thickness from one end to the other. This arrangement ismade only in view of saving metal.

The inner confronting lower corners of the base portions 8 of the chairsections are rounded, as at. 8, which permits of a determined tilting orcanting of the sections with respect to each other when the lockingplate and key, hereinafter described, are removed. In this manner thechair sections may be readily arranged in rail engaging position. I

The base 8 of each of the chair sections has, approximately at thecenter theerof, a transverse slot 9 which enters from its outer face andwhich communicates with openings 10 in the portions of the base inwardof the side members 4. The slots 9 are of a size to receive freelytherethrough a locking plate 11. The plate 11 has its ends formed withextensions 12, the said extensions being spaced away from each other adistance to permit of the inner straight edges 13 thereof contactingwith the outer straight faces of the side plates 4 of the respectivechair sections, when the locking plate has been moved upwardly by a key14 that is also passed through the slots 9 and has its upper edgecontacting with the lower edge of the locking plate 11. Suitablesecuring means, preferably in the nature of cotter pins 15 pass'throughopenings in the key 14 for retaining the same on the chair.

The numeral 16 indicates the wedge which I employ. The wedge has itsupper face flat, as indicated by the numeral 17, and its under andinclined face rounded downwardly from its edges to its center asindicated by the numeral 18. The rounded portion 18 of the wedge restson the upper face of the base of the chair sections, and exerts a tight3O mined outward pressure against the hooked frictional engagementbetween the said base through. These openings 20 receive therethroughrods 21 respectively. Each of the rods has a threaded end 22 on which isplate.

screwed a nut 23, each of the said nuts contacting one end of aconvolute spring 24: that is arranged between the said nuts, and theprojections or lugs 12 on the locking The threaded end of each of therods 21 is provided with a series of apertures, and through one of theseapertures there is passed a cotter pin 25 that contacts with the outerface of the nut to hold the nut from unscrewing. The opposite end ofeach of the rods 21 is bent at an angle, as indicated by the numeral 26and is directed toward the wedge. The extremities of the angle ends 26are bent upon themselves to provide hooks 27 that are received in theapertures 19 in the Wedge plate. By this means, it will be noted thatthe wedge is effectively sustained in wedging position, and it will alsobe apparent that a deterends of the rods will compress the springs topermit of the disengagement of the rods with the wedge plate, whichpermits of the said plate being forced from between the chair and rails,after the removal of the key 14 from the chair sections to permit of theremoval of the rails from the chair. The rails are supported ontieswhich are disposed to the opposite sides of the rail joint, and thevibration of the rolling stock passing over the rails at the jointwillcause the railchair described and hold the confronting toautomatically grip the rail, as heretofore ends of the rails in properalinement.

Having described the invention, I claim 1. A rail chair, comprising twocompanion sections each including a base, upstanding flanges at theupper edges thereof providing side plates and inwardlydirected' flangeson the upper edges of the said side plates, removable means connectingthe bases of the chair sections for holding the chair in rail receivingposition, awedge member hav ing a rounded lower face between the base ofthe rails and the base of the chair sections, and spring influencedmeans between the wedge and the connecting means for the chair sectionsfor securing the wedge on the chair and in frictional engagement withthe base of the rails.

2. In combination with two connected rails, of a rail chair therefor,comp-rising two similar sections each including a base, "a side and aninturned flange formed-on the side, the base portions of the chairsdecreasing in thickness from one end thereofto the other end, the basesof said chairs having of the chair sections and the base of the rails,and spring influenced means between the widened end of the wedge and theends of the locking plate for holding the wedge in wedging position withrespect to the chair and with respectto the rails.
